I have a problem with my JBL PB12, I have read lots of threads and see that they are pretty much lemons. I have had mine for about 6 years with no problems until now. The red lights come on in the front, and eventually turn green when watching movies, but little to no base is coming out of it during the movie. When the sound ends the lights go red and there is a noticeable humming. Anyone else have this problem? I figure it is toast and planning on replacing it with a CSX-12 or BIC H100 anyhow, but this just expedites that process.
